Patagopteryx

                 Patagopteryx deferrariisi fossils have been
                found in Patagonia located in Late Cretaceous 
                sediments.  It has been described as having a
                robust body with small wings and referred to as 
                a chicken-size flightless bird with a body length 
                of approximately 2.5 ft. (Feduccia 1996, Alvarenga
                and Bonaparte 1992). 

                Patagopteryx is considered an intermediate form 
                between dinosaurs and modern day birds.
